Abstract: A method for cleaning a photoreceptor of an image forming apparatus comprises the steps of actuating cleaning means of a cleaning system (8) and rotating the photoreceptor (1) before a usual image forming operation, after a predetermined time charging a particular area of the photosensitive drum (1), causing residual toner adhering to a sealing member (10d) of a developing unit to attract to the charged area, carrying the attracted residual toner with rotation of the photoreceptor to the cleaning means of the cleaning device (8), and removing the residual toner by the cleaning means. Accordingly, the present invention eliminates the possibility of mixing of colour of previously used toner into a toner image after replacement of a developing unit by another unit containing different colour of toner.

Inventor: LOREN NORMAN ESQ
IPC: B60B7/12
Filed: 1987-09-22
Abstract: A wheel cover mounting for plastic wheel covers (10) comprising a mounting portion (14) positioned in axial alignment with and spaced radially inward from a facing surface portion (16) of a vehicle wheel (18). A spring wire retainer ring (32) including radially outwardly extending projections (34) spaced circumferen­tially around the ring (32) in a substantially flat plane are received through circumferentially spaced openings (73, 77) in the mounting portion (14) of the wheel cover (10). At least one, and preferably most if not all, of the openings (73, 77) are defined by guide walls (72, 74, 76, 78) circumferentially spaced apart a distance greater than the circumferential width of the projections (34) in order to reduce frictional forces between the projections (34) and the lugs (20-30) and maximize the forces retaining the wheel cover (10) on the wheel (18) and in a fixed position with the wheel (18). The forces maintaining fixed positioning can be further increased by anti-rotational means (38) interposed between the wheel cover (10) and a surface (16) fixed for rotation with the wheel to resist relative rotational displacement of the wheel cover (10) with respect to the wheel (18). Preferably, two spring clips (38) including a resilient tang (58) are disposed at diametrically opposed positions of the wheel cover (10) with their tangs (58) radially inclined in opposite rotational directions. The openings (73) in the mounting portion near the spring clips are defined   by guide walls (72, 74) spaced apart from each other a distance greater than the width of the projection (34) extending through the opening so that the loading force of the spring clip (38) does not affect the retaining force applied by the spring wire re­tainer (32).

Abstract: A method for using an underground mine communication system to effect minewide communication and an intrinsically safe current limiter circuit for insuring that electrical equipment in the system will not cause incendiary conditions. The underground mine communication system comprises a plurality of repeaters (28) and medium frequency radios, including mobile (24), portable and personal-carried radios (26), coupled to electrical conductors (32) and natural waveguides existing in the earth by tuned loop antennas. Messages transmitted by the radios are carried to the repeaters by the conductors or coal seam waves. The repeaters amplify, replicate and retransmit the message at two different frequencies for transmission of the message to a surface base station and to other radios in the system. A paging system, which has a separate set of repeaters (29), is also coupled to the network of electrical conductors and natural waveguides by tuned loop antennas. The paging system alerts miners to contact the surface base station. Radios, pagers and repeaters in the system are equipped with the intrinsically safe current limiter circuit to preclude the development of incendiary conditions. The current limiter circuit comprises a series arrangement of a current trip circuit, a redundant current trip circuit and a current limiting field effect transistor controlled by a feedback control amplifier.

Abstract: In this computer system, a plurality of processing elements (PE), each having at least two channel processors (ch.P) which manage corresponding communication channels separately, are connected in a ring via the channel processors to form a processing element loop (10). Some of the processing elements are designated as process managers (SM₁ - SM n ) which manage the corresponding process frame groups (20) comprising a predetermined number of process frames. At least one other element is designated as a master manager (MM) which manages those process managers. The respective process managers (SM₁ - SM n ) each allocate a predetermined process to any one process frame of the process frame group (20) which that process manager manages in accordance with each requirement from the master manager (MM) to cause that process frame to execute the predetermined process. Thus both of the function and load decentralizing functions as a computer system are satisfied on the basis of the function of the master managers (SM₁ - SM n ) and process manager (MM).

Abstract: A process for determining the geometry of an object (10) in a forging press is specified, it being the case that for the purpose of being processed the object in the forging press is displaced for a processing pass and rotated about the longitudinal axis in a predetermined fashion. In this process, the surface of the object (10) is continuously scanned over the circumference in a manner known per se in planes perpendicular to the direction of displacement of the object. Thereafter, the scanned data are transmitted to a computer programmed in advance, and subsequently converted in the computer with the aid of a program based on the volume constancy conditions in such a way that the actual geometry of the object (10) is acquired. The acquired actual geometry is processed in the computer so as to introduce a further transformation step with predetermined programmed forging parameters. A device for carrying out the process consists of a carrier, which is constructed as a ring (13), is arranged in the vicinity of the processing region of the object (10), and is attached to a sensor (15), rotating about the object at a defined rate. Installed on the inner surface (14) of the ring (13) at two or more oppositely located points are beam transmitters (11) and beam receivers (12) arranged adjacently in each case.

Abstract: Methods and apparatus are disclosed for rapid and interactive "warping" of a first image made up of pixels to form a resulting image made up of pixels which are aligned, pixel-for-pixel, with a second image made up of pixels. The images may be stroboscopic voltage contrast images representing operating states of two integrated circuit devices -- a failing device and a fully functional device. The aligned images permit an engineer who may have little knowledge of the device to diagnose dynamic failures of the failing device by comparing the aligned images to produce an image showing the differences. The invention is preferably carried out as a series of processing steps on a standard, general purpose engineering workstation. In accordance with the invention, two images are displayed on a screen. The locations of three features of the first image are selected and marked (with sub-pixel precision) for alignment respectively with the locations of three selected features of the second image. A geometric planar transformation matrix is calculated which maps the features of the first image into those of the second image. The values in the transformation matrix are then converted into fixed point representations which are used, as the resultant image is scanned line, to transform positions of the first image into pixel positions of the resultant image. Pixels outside the display field of the resultant image are assigned a black intensity value. Since pixel positions of the resultant image may not coincide with pixel positions of the first image, the intensity value of each pixel of the resultant image is extrapolated (using weighted averaging based on distance) from the values of the four pixels of the first image surrounding the location of the first image which corresponds to the pixel of the resultant image. The resultant image may be compared, pixel-for-­pixel, with the second image to show differences between the images.
